UBS says AI infrastructure stocks outpaced hyperscalers 6-to-1

AI infrastructure stocks created 6 times more value than big tech hyperscalers over the past four years, a UBS research report found.

AI infrastructure companies generated 600% value creation since 2022, compared with 100% for hyperscalers such as Amazon, Microsoft and Google, according to UBS's research arm — a shift in where AI investment returns are concentrated.

"The value creation in AI infrastructure has dramatically outpaced the hyperscalers themselves, marking a structural change in how the AI supply chain captures economic returns," the UBS research team wrote in a report published July 3.

The finding comes as AI infrastructure stocks have surged in 2026. Sandisk gained 857%, Micron Technology rose 304% and Intel climbed 278%, according to data compiled by Investor's Business Daily. Western Digital, Marvell Technology, Seagate Technology and Dell Technologies each more than doubled. The seven S&P 500 components have benefited from surging demand for memory chips, data center equipment and custom AI processors as cloud providers race to build out capacity.

The UBS analysis suggests the $200 billion-plus AI infrastructure buildout is generating returns disproportionately for suppliers rather than the cloud platforms footing the bill. That could fuel further capital rotation into semiconductor and data center stocks, while raising questions about the return on investment for hyperscalers spending tens of billions annually on AI.

Infrastructure Suppliers Capture the Upside

The UBS report quantifies what investors have sensed: the companies building the physical layer of AI — memory chips, networking gear, servers and data center power systems — are capturing a growing share of the AI economy's value. Memory chipmakers have been the standout beneficiaries. NAND and DRAM prices have surged 200% and 300%, respectively, over the past year as hyperscalers compete for limited supply, according to JPMorgan Chase strategist Meera Pandit.

Micron's revenue jumped 345% in the May quarter, while Sandisk's sales rose 251% in the March period. Both companies guided sharply higher for the current quarter. The supply shortage is so acute that Nvidia has invested more than 250,000 GPUs into CoreWeave's data centers alone, the neocloud provider disclosed.

Can the Cycle Sustain?

The memory chip industry has historically been defined by boom-and-bust cycles, with periods of supply scarcity followed by oversupply and price collapses. Wall Street expects memory chip sales to peak in 2028, after which Micron's adjusted earnings could decline 27% in fiscal 2029 and Sandisk's by 54%, according to analyst estimates cited by The Motley Fool.

Micron trades at 24 times earnings, while Sandisk trades at 67 times — a premium that reflects the magnitude of the current upcycle but leaves little room for error if demand normalizes. The UBS report did not address the cyclical risk directly, but the valuation gap between infrastructure suppliers and hyperscalers suggests the market is pricing in sustained growth rather than a repeat of the 2022-2023 downturn, when memory stocks fell 50% to 60%.

For investors, the UBS analysis supports a rotation that has already reshaped the S&P 500's leadership. AI infrastructure names now command a combined market capitalization exceeding $3 trillion, with Micron alone valued at $1.29 trillion. The question is whether the 600% value creation figure represents a peak or a waypoint. Nvidia, the largest AI infrastructure supplier, trades at 21 times forward earnings — a discount to its growth rate that suggests the market sees room for further gains even as the cycle matures.
